Could it be that you updated the module or that you have other marketplace modules within you application. Because it can be that the libraries conflict with eachother or are actually missing:
First steps to do:
1. check your userlibs for having two of the same userlibs
2. create a separate project where you only download the specific marketplace module, try to run the project and check these userlibs and compare them with your userlibs is there missing anything try to add it.
